Lexical bindings

;;; -*- lexical-binding: t; -*-Dir local variables
Disable these because I don't use them and don't want to get prompted by them in some projects.
(setq enable-dir-local-variables nil)Taking SVG screenshots
Since Emacs 27, we can take SVG screenshots! Emacs needs to be built with
cairo to support this.
(defun screenshot-svg ()
"Save a screenshot of the current frame as an SVG image.
Saves to a temp file and puts the filename in the kill ring."
(interactive)
(let* ((filename (make-temp-file "Emacs" nil ".svg"))

Main theme
A list of all doom themes can be found here:

(setq doom-theme 'doom-solarized-light)Dark theme toggle
I've come to prefer using a light theme during the day, and a dark theme at night. Using a dark theme with daylight leads to cranking up the screen brightness, which hurts my eyes more than using the light theme.
Set my light and dark themes:
(setq my/light-theme doom-theme
my/dark-theme 'doom-one)Function to toggle between the two easily:
(defun my/toggle-dark-theme ()
(interactive)
(if (eq my/dark-theme doom-theme)
(load-theme my/light-theme t)
(load-theme my/dark-theme t)))
Bind this to SPC t d:
(map! :leader
(:prefix-map ("t" . "toggle")
:desc "Dark theme" "d" #'my/toggle-dark-theme))Font
Doom exposes five (optional) variables for controlling fonts in Doom. Here are the three important ones:
doom-fontdoom-variable-pitch-fontdoom-big-font– used fordoom-big-font-mode; use this for presentations or streaming.
They all accept either a font-spec, font string (Input Mono-12), or xlfd font
string. You generally only need these two:
(setq doom-font
(font-spec :family "Iosevka Fixed" :size 10.0 :weight 'medium))Line numbers
Possible values of display-line-numbers-type are nil, t, and 'relative.
(setq display-line-numbers-type 'relative)Battery indicator
I'm on a laptop, so let's display my battery in the modeline:

Disable smart parens because half of the time it doesn't do what I want:

Column width
rustfmt limits lines to 100 characters, let's display it correctly.
(add-hook! rustic-mode

The default is "check", but I want clippy lints as well.

I don't want to see archival files appearing when listing files in the current directory, so hide them by default.
(after! org
(setq org-archive-location ".%s_archive::"))Agenda setup
Default task keywords
Here are the keywords I'm using to track task progress. I'm also making use of some automatic state changes.
| keyword | meaning |
|---|---|
TODO |
Self explanatory |
DONE |
This task is finished, no longer displayed in the agenda |
CANCELLED |
This task isn't finished but is no longer relevant |
(after! org
(setq org-todo-keywords
'((sequence
"TODO(t)"
"|"
"DONE(d!)"
"CANCELLED(c@/!)")
(sequence
"[ ](T)"
"|"
"[X](D)"))))Org capture setup
Of course I also need to setup capture templates:
The first one just prompts me for a new task to add to my inbox, I can then refile them where I want later.
The second one exists because I like to keep a separate list of articles / papers / books to read.
(after! org
(setq org-capture-templates
'(("t" "New entry" entry (file "inbox.org")
"* TODO %?")
("T" "Task" entry (file+headline "tasks.org" "Misc")
"* TODO %?")
("r" "Reading" entry (file "reading.org")
"* TODO %x"
:immediate-finish t)
("w" "Watching" entry (file "watching.org")
"* TODO %x"
:immediate-finish t))))
I also change the default Doom binding for #'org-capture to be SPC x instead
of SPC X. Also need to rebind what was previously bound to SPC x, to SPC
X.
(map! :leader
:desc "Org Capture" "x" #'org-capture
:desc "Pop up scratch buffer" "X" #'doom/open-scratch-buffer)Main agenda view
All these tasks, once captured, are then centralized in my agenda view.
I'm using multiple categories to organize tasks, depending on their triage / status (inspired by https://blog.jethro.dev/posts/org_mode_workflow_preview/).
(after! org-agenda
(setq org-agenda-custom-commands
'((" " "Agenda"
((agenda ""

)))))I want the default agenda view to be a weekly view, with a log of what I've done during the day.
(after! org-agenda
(setq org-agenda-span 'week)
(setq org-agenda-start-on-weekday 1)
(setq org-agenda-start-with-log-mode '(clock)))I also remove the block separators in the agenda view:
(after! org-agenda
(setq org-agenda-block-separator ""))Habits
Let's enable the org-habit module:
(add-to-list 'org-modules 'org-habit)Save all org buffers shortcut
By default bound to C-x C-s, rebind it to SPC m s in org-agenda-mode :
(map! :after org-agenda
:map org-agenda-mode-map

Setup for org-roam.
Roam Directory
First, set a directory where org-roam will index things.
(setq org-roam-directory (expand-file-name "notes/" org-directory))Export backends
Sometimes I need to export an Org subtree to a file, which is quite easy with
the org export backend. It doesn't seem to be enabled by default, so let's add
it to the list:
(after! org
(add-to-list 'org-export-backends 'org))Doom specific
Doom makes some changes to org-id behaviour which I don't like / think are necessary.
(after! org
(setq org-id-locations-file (expand-file-name "~/.config/emacs/.org-id-locations"))
(setq org-id-locations-file-relative nil))Doom replaces the default tab behavior on headings, this restores the default one. Taken from here.

(remove-hook 'org-tab-first-hook #'+org-cycle-only-current-subtree-h))Magit
Gitlab CI skip flag
This option tells GitLab to skip the CI run for this push, in case I know it's not ready yet.
(after! magit

This setting instructs mu4e to prompt for login credentials if none are found
when trying to connect to one of the servers that match the regex (see variable

Disable org-msg by default
Doom adds a hook, making it impossible to disable. This allows us to toggle it manually.
(after! org-msg
(setq +mu4e-compose-org-msg-toggle-next nil))Message quoting style
Has to be duplicated because mu4e doesn't use message-cite-style's values.

(after! mu4e
(setq mu4e-compose-format-flowed nil))Don't permanently delete when trashing mails
By default mu4e sets the trashed flag on emails trashed using the d
keybinding. This just replaces the action to just move the message to the trash
instead.
See https://github.com/djcb/mu/issues/1136#issuecomment-1066303788, the code will have to be adapted soon.
